Gas drilling involves three methods: dry gas, spraying and foaming. Among them, spray and foam drilling are mainly used in layers that are not suitable for dry gas drilling, to increase the cutting capacity of the circulating medium. Spray pump is a special device for drilling spray foam. It mainly provides the foam base fluid under high pressure and set speed for spray drilling and foam drilling in gas drilling.It is an important key equipment for gas drilling. During spray/foam drilling, the compressed gas from the gas pumping equipment and the liquid from the liquid pumping equipment are mixed through a mixing device to form a homogeneous gas mist or foam liquid that passes through the stand, drill rig, borehole and the troublesome borehole trunk space. It then passes through the well mouth and the plug manifold (or directly through the side port of the rotating head and the feed line) and then enters the exhaust basin or through a closed gas, liquid and solid circulation system. Separation.

The flow rate of the sprayed base liquid pump is steplessly adjusted in the range from 0 to 360 l / min; it can operate as one pump or two pumps simultaneously in gas spray drilling; the control system displays and controls the flow, pressure and pressure; Rush pump manual local control and remote control from central control, local control operates autonomously. The foam generator and control system are an independent unit. The high pressure gas interface is connected to the amplifier. The high-pressure liquid interface is connected to the spray base liquid pump. The outlet of the formed gas foam is connected to the well mouth.gas foam drilling operations; The rated pressure and rated power consumption of the generator are produced according to the requirements. The foam generator control system displays the flow rate, pressure, temperature, density, and the density of the foam liquid is controlled by PLC, electric drive;  , etc. d. The chemical injection pump can be independently integrated into the gas drilling spray and foam grinding device, which is used to perform technical services such as gas spray drilling and gas foam drilling under relatively harsh operating conditions.

Purpose: The pump is suitable for use in petroleum, chemical and fertilizer industries as process pumps, metallurgy and steel mills. Pressure water sludge removal, cleaning and high pressure water sludge removal in construction, shipbuilding, sugar, paper, chemical and other industries. It is necessary to pump water at oil fields, boiler water supply, hydraulic equipment power supply, as well as food, pharmaceuticals, etc. d. Liquid part of high pressure. The transport medium is liquid and contains no solid particles.
